Renesas R5F524TAAGFP#31

Overview

R5F524TAAGFP#31 from Renesas is a 32-bit RXv2 core MCU optimized for motor control and industrial inverter applications, operating at 80 MHz (153.6 DMIPS), featuring integrated FPU (IEEE 754 compliant), 256 KB on-chip flash, 16 KB SRAM, and 8 KB data flash with 1M erase/write cycles. It delivers three-phase complementary PWM ×2 channels + single-phase complementary ×4 channels via MTU3 and GPT timers, and supports CAN (ISO 11898-1) for real-time fieldbus communication.

For engineers reviewing the R5F524TAAGFP#31 datasheet, R5F524TAAGFP#31 pinout, R5F524TAAGFP#31 application, or R5F524TAAGFP#31 equivalent, key selection considerations include its 100-pin LFQFP-0.5 mm package, 12-bit ADC with 3-channel synchronous sample-and-hold (unit 1), programmable gain amplifier (1+3 channels), and IEC60730-compliant self-diagnostic features for functional safety-critical motor drives.

Technical Context

The R5F524TAAGFP#31 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its clock system integrates PLL (4–12.5 MHz input), on-chip high/low-speed oscillators, and CAC for real-time clock accuracy monitoring across ICLK (80 MHz), PCLKA (80 MHz for MTU3/GPT), and PCLKD (40 MHz for S12AD).

Peripheral integration centers on motor control: MTU3 provides 9×16-bit timer channels with dead-time compensation, reset-synchronized PWM, and A/D start triggering; GPTB adds 4×16-bit channels supporting cascaded 32-bit operation and comparator interlocking. The MCU includes POE3A for safe high-impedance control of MTU3/GPT waveform outputs during fault conditions.

What is the maximum operating frequency and DMIPS rating of the R5F524TAAGFP#31?

The R5F524TAAGFP#31 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance using the RXv2 CPU core. This benchmark reflects real-world execution of mixed instruction workloads including integer, floating-point, and DSP operations-enabling deterministic execution of complex motor control algorithms such as field-oriented control and predictive current regulation within tight timing budgets.

Does the R5F524TAAGFP#31 support simultaneous sampling for motor current measurement?

Yes, the R5F524TAAGFP#31 supports simultaneous sampling via the 3-channel synchronous sample-and-hold circuit in S12ADF unit 1. This allows concurrent acquisition of U/V/W phase currents-essential for accurate vector control-and is triggered by hardware signals from MTU3 or GPT timers to align precisely with PWM switching edges.

What safety certifications or functional safety features does the R5F524TAAGFP#31 include?

The R5F524TAAGFP#31 includes multiple IEC60730-compliant features: ADC self-diagnostic and analog input disconnection detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, memory protection unit (MPU), and register write protection. These features collectively support Class B compliance for household appliances and industrial equipment without requiring external safety monitors.

Which communication interfaces are available on the R5F524TAAGFP#31 for industrial networking?

The R5F524TAAGFP#31 integrates CAN (1 channel, ISO 11898-1 compliant), SCIg (3 channels supporting UART, SPI, I2C, and smart card modes), RIIC (1 channel, 400 kbps SMBus-compatible), and RSPI (1 channel, 20 Mbps). These interfaces enable robust fieldbus connectivity-including CANopen and Modbus RTU-while supporting local sensor interfacing and debug communications.

What is the package type and pin count of the R5F524TAAGFP#31?

The R5F524TAAGFP#31 uses a 100-pin LFQFP package (PLQP0100KB-B) with 14 × 14 mm body size and 0.5 mm pin pitch. It provides 81 general-purpose I/O pins, including 5-V tolerant inputs and open-drain outputs, making it suitable for direct interfacing with industrial-level 24 V logic and gate driver ICs in motor drive applications.
